//! Theme Toggle component - switches the document between light and dark.
//!
//! A single icon button: moon while the page is light, sun while it is dark.
//! Clicking flips the `dark` class on `<html>`, mirrors `color-scheme`, and
//! persists the choice under the `theme` localStorage key; with nothing
//! stored, the runtime follows `prefers-color-scheme`.
